CNVERTIBLE SELF-CLOSING ND COMPRESSION COCK.

To all who/m, 'it may concern.'

Be it known that l, ANTON C. Sentinenaivn, a citizen of the United. States, residing at Decatur, in the county of Macon and State of illinois, have invented newand use lo' be operated either as ay non-automatieally closing cool: al'ter -the'mannor of a compression cock` or plug cock, or as an automatically or self-closing cock, and is convertible from one to the other at will.

There are many instances in which a purchaser or a. dealer desires to change the operation of the oook. Among thfese instances maybe mentioned particularly instances inv hotels where customers desire to use running water at the lavatories. And 1n any vcaee where it isy at times desired to maintain a regulated fiow of water this change is desirable.

By means of my invent-ion, a self-closing cook may be opened or closed to any desired degree and will remain opened or closed at any position.

in the aeeomplislnnent ot my invention lf provideI a noch with a movable part adapted normally to operate the cook as an antolnatically or eelt-closing cook. l provide further a means eonnn'issing a movable part adapted to cooperate with the first named movable part to ope 'ate the valve as `a"non-. automat' tally closing falve and by which the valve is manually operated to all posi-- tions and eet in these positions a't'ter the manner ot a compression eoek. Together with these provisions, means by which said movable parts can be connected and die connected at will secures to me the attainment ot my invention.

lt will be apparent upon an understantb ing; of my invention that my convertible automatically or eelt-elosing` and non-autonnitieally closing,r cock eompriszee an automatically or self-closing,` operating means, and a non-automatieally closing' or compression operating means, said latter means comprising` a member for interlocking two parts thereof together. Structural details ot' invention also find place in the embodiment I disclose.

cook ot my invention showing the valve in closed position and the non-automatically closing operating means in use. Fig. 2 is a. transverse section of Fig. l, showing the same mechanism in operation and the valve open. Fig. 3 is a partial section similar to Fig.l l showing the automatically or selfclosing` operating means in use with the valve closed. and Fig'. 1l is a section similar to Fig. 25 showing the same operating means muse and the valve open.

Referring to the drawings, l0 is the valve asing, Til the valve, and 12 the valve seat of the cock. illissociated with the valve l1 is the usual stem i3, and grouped around this stem are `the various elements of an automatically or sett-closing operating means. As shown this means comprises a fixed traekway i4. a movable trackway i5 eonneeted to the stem, and provided with van 'operating handle 16, and intervening' rollers li' for causing the opening of the valve upon the turning' of the handle. Upon the releaee ot' the handle the valve is closed hy a spring i8 which is; placed under tensit'n b v the opening ofthe valve, tne spring` being` confined between the valve ll and an abutment lll on the easing. Other details there are to this seltelosing tmerating` means. but they need not be mentioned in connection with this invention. Also grouped about the stein are the elements oi the non-automatically closing' operating' means. This means Coniprieos the gland nut- '20 or other tixed part which is provided with a ,-:erew-tln'ead Qi al its upper end. 'lhe lower traehway lll. inelezul oit being,` Formed on :i pernnanently fixed part. as tor instance on the bodaY oit the. gland Q0 it elf, as' is usual, is formed separately and with a eup portion receiving' the upper end ot the gland nut and being interiorly ,screw threaded to engage the threads 2l of the gland nut. lt should be evident that if the member il is turned so as to withdraw it away troin the gland nut, the upper trackwaj' l5 will be rairuxd by movement of the rollers 1T between the lower and upper traclnvays. The handle lll Carries' a bonnet '23 inelosing the traekways nl and 15 and the rollers. l? to prevent accumulation of dirt and the like thereon. By interlocking means which lY h ave provided. ln'nvever7 the setti-clotting oooh'y may loe made 'to operate as a nenentomatieally cioeing ceci; by the litltl lill@ Q. the depending bonnet or apron I23 of thehandle 16 which is confined by the abutment 24, on the valve stem. This member 22 is adapted to bear against a shoulder 25 on. the lower trackway 14, and when screwed ,up firmly Within the bonnet 23 actsto clamp the` lower and upper trackivays together 'and upon the intervening rollers 17, wherewhich the valve is shown operated as a nonupon both trackivays vvill turn together. This situation is shown in Figs. l and 2, in

automatically-closing cock. In Fig; .l the valve is'shoivn closed, and vthis closure is maintained by vthe spring 18. llvhen the operating handle is turned in the opposite direction, the screw threads of the moving part let act to raise the valve from its seatagainst the pressure of spring 18, as shown in Fig. 2. Y

In Figs. 3 and L1- the valve is shown operating as a self-closing cock, the self-closing operating means acting automatically to7V f close the cock i n,the well known manner.

As isclearly seen invFigs. 3 and4 the interlocking or connecting member 22 is removed from engagement with the bonnet 23and from engagement With the abutment 25'onthe lower tracl iway.-A The operatinn as a self-closing cock is therefore free from interferenceeby the connecting member 2Q.

lVhile I have described the best forms of my invention now" known to me, and' have described it in connection with a cock designed normally to operate as a self-clos- Y ing cock, it should'be evident that many changes maybe made in the construction by thoseskilled in the art, andthat it may as Well be applied and that Without departing in any Wise from the generic spiritof my invention, to `a cock which normally operates as a non-automatically closing cock] I desire to cover in the annexed claims all such modifications as fall )vithin the legal purview of my invention. f
